An energy absorber includes a housing, a bearing housing positioned within the housing, a main connection point connected to a first receiver, and a threaded rod connected through a bearing and having an end connected to the first receiver at a first end of the housing. The bearing is positioned in the bearing housing. Compressible elements of the threaded rod compress against the bearing to absorb energy upon exceeding a force threshold.

A bicycle saddle suspension assembly comprises a body configured to couple to a bicycle frame; a saddle support mechanism configured to couple to a bicycle saddle; a suspension spring that biases the saddle support mechanism in a first direction with respect to the body; and a damping apparatus configured to damp motion of the saddle support mechanism with respect to the body, the damping apparatus configured to reduce a level of damping responsive to a terrain-induced force.

A front fork leg includes an inner chamber that absorbs by a gas spring a shock caused on a vehicle; an auxiliary gas spring chamber communicating with the inner chamber; an auxiliary piston provided in the auxiliary gas spring chamber; and a gas spring chamber side gas chamber sectioned by the auxiliary piston and communicating with the inner chamber, and the auxiliary piston moves to increase a volume of the gas spring chamber side gas chamber, as pressure inside the inner chamber increases.

A vibration isolator includes a housing forming an internal cavity, an elastomeric diaphragm within the internal cavity, the elastomeric diaphragm combining with a first end of the housing to form an air spring within the internal cavity, a mechanical spring in series with the air spring within the internal cavity; a mount in series with the mechanical spring opposite the air spring, an annular elastomeric stopper between a second end of the housing and the mount, wherein the mount and the annular elastomeric stopper combine to seal the second end of the housing to form a chamber within the internal cavity between the elastomeric diaphragm and the second end of the housing, and a plate seated on the mount within the chamber.

A shock device for an at least partially muscle-powered two-wheeled vehicle, including at least one tube system having two telescopic tubes, the tube system extending from a first end to a second end. A suspension system is provided which is effective between the two ends and which biases the two tubes to an extended position. The suspension system includes a positive air spring and an independent, series-connected supplementary spring. Both the positive air spring and the supplementary spring bias the tube system to the extended position. The supplementary spring shows a lower breakaway force than does the positive air spring, and the ratio of the suspension travel of the positive air spring to the suspension travel of the supplementary spring is higher than 4:1.

A vibration isolating device that is adapted for an elastic coupling of a first component to a second component and for vibration isolation in predetermined frequency ranges between the first and second components, the vibration isolating device comprising at least a first and a second elastically deformable plate that are attached to each other in at least two separate connecting points, the first elastically deformable plate comprising a first curvature and the second elastically deformable plate comprising a second curvature, wherein the first and second curvatures are respectively located in a region between the at least two separate connecting points and arranged such that a gap is defined between the first and second elastically deformable plates.

A vibration isolating device that is adapted for an elastic coupling of a first component to a second component and for vibration isolation in predetermined frequency ranges between the first and second components, the vibration isolating device comprising at least a first and a second elastically deformable plate that are attached to each other in at least two separate connecting points, the first elastically deformable plate comprising a first curvature and the second elastically deformable plate comprising a second curvature, wherein the first and second curvatures are respectively located in a region between the at least two separate connecting points and arranged such that a gap is defined between the first and second elastically deformable plates.

A vibration ring is provided to remove vibratory energy from a machine driveline. The vibration ring includes a compression cage configured to generate vibratory excitation within a material. The material is configured to generate an electric charge dissipated through or harvested by an electric circuit.

A movable axial element for a damping system includes a rectilinear absorbent mass positionable in the housing and having at least one annular groove arranged on a periphery of the absorbent mass and in which at least one elastic element is arranged to bear against an internal wall of the housing. The at least one groove includes a base formed by a shoulder of the absorbent mass. An edge formed by a structure bearing an annular lip is mounted in a sliding manner on at least one part of the shoulder along at least one axis of the movable element to form an adjusting device integrated into the movable element to enable the control of a prestressing exerted by the annular lip on the elastic element mounted on the periphery of the absorbent mass, the prestressing being generated without rotation of the annular lip relative to elastic element.

Systems, methods, and devices of the various embodiments provide a compact vibration damper configured to be remotely-tunable and/or self-tuning. In various embodiments, a flywheel may be coupled to a shaft that spins a rotary damper. A linear actuator may operate a scissor assembly that moves the flywheel thereby changing the mass moment of inertia of the spinning flywheel without changing the actual mass of the flywheel. The linear actuator may move the scissor assembly and flywheel to tune the compact vibration damper. In additional embodiments, opposing rotary springs may be coupled to the shaft that spins the rotary damper.
